Nepal\'s military consists of the Nepalese Army, which includes the Nepalese Army Air Service. The Nepalese Police Force is the civilian police and the Armed Police Force Nepal is the paramilitary force. Service is voluntary and the minimum age for enlistment is 18 years. Nepal spends $99.2 million (2004) on its military—1.5% of its GDP. Much of the equipment and arms are imported from India. Consequently, the US provided M16s M4s and other Colt weapons to combat communist (Maoist) insurgents. As of now, the standard-issue battle rifle of the Nepalese army is the Colt M16.

Nepal has close ties with both of its neighbours, India and China. In accordance with a long-standing treaty, Indian and Nepalese citizens may travel to each others\' countries without a passport or visa. Nepalese citizens may work in India without legal restriction. However, since the Government of Nepal has been dominated by Socialists and India\'s by more right-wing parties, India has been remilitarizing the \"porous\" Indo-Nepali border, in order to stifle the flow of Islamist groups. Nepal established relations with the People\'s Republic of China on 1 August 1955, and relations since have been based on the Five Principles of Peaceful Coexistence. Nepal has aided China in the aftermath of the 2008 Sichuan earthquake, and China has provided economic assistance for Nepali infrastructure. Both countries have cooperated to host the 2008 Summer Olympics summit of Mt. Everest. Nepal has assisted in curbing anti-China protests from the Tibetan diaspora.
